Ingredients You’ll Need
Getting the flavors just right in this dish depends on a handful of simple yet essential ingredients. Each one contributes something special, whether it’s the silky texture of roasted squash, the zesty brightness of fresh lemon, or the crunchy warmth of toasted hazelnuts.
- Butternut squash (or preferred squash): Provides a sweet, tender base that caramelizes beautifully in the oven.
- Olive oil: Helps everything roast evenly while adding a subtle fruitiness.
- Maple syrup (or honey): Creates the perfect golden caramel coating with a rich sweetness.
- Ground cinnamon: Adds warm spice notes that complement the natural squash flavor.
- Cayenne pepper: Brings a gentle heat to balance the sweetness—adjust to taste.
- Salt and black pepper: Essential for seasoning and enhancing all other flavors.
- Lemon zest and juice: Adds a bright, citrusy contrast that lifts the entire dish.
- Hazelnuts: Toasted for crunch and a buttery, nutty flavor.
- Fresh parsley (optional): For a pop of color and fresh herbal aroma.
How to Make Spicy Caramelized Squash with Lemon and Hazelnuts Recipe
Step 1: Preheat Your Oven
Start by setting your oven to 425°F (220°C). A hot oven is key to getting that beautiful caramelized exterior on the squash cubes, sealing in their natural sweetness while creating a slightly crisp edge.
Step 2: Prepare the Squash
Peel your butternut squash carefully, remove any seeds, and chop it into roughly 1-inch cubes. Uniform pieces ensure they cook evenly and caramelize at the same rate.
Step 3: Season the Squash
In a large mixing bowl, toss the squash cubes with olive oil, maple syrup, cinnamon, cayenne pepper, salt, and freshly ground black pepper. Make sure every cube is generously coated so that every bite is bursting with flavor and warmth.
Step 4: Arrange on Baking Sheet
Line a baking tray with parchment paper, then spread the cubes out in a single layer. Avoid crowding; this allows hot air to circulate and helps the squash caramelize rather than steam.
Step 5: Roast to Perfection
Roast the squash for 25 to 30 minutes, turning halfway through. You’ll know they’re ready when the cubes are tender inside and golden brown with that irresistible caramelized crust.
Step 6: Add Bright Lemon Flavor
Once out of the oven, sprinkle the squash with fresh lemon zest and squeeze over the juice. Gently toss to combine, letting the citrus brighten and balance the rich flavors.
Step 7: Toast the Hazelnuts
While the squash is roasting, toast the hazelnuts in a dry skillet over medium heat. Stir frequently for 5 to 7 minutes until they turn golden and release their nutty aroma. This step adds a lovely crunch that contrasts beautifully with the soft squash.
Step 8: Combine and Serve
Fold the toasted hazelnuts into the lemony squash mix, mixing carefully to avoid mashing the cubes. Transfer everything to a serving dish and, if desired, sprinkle with fresh parsley for a vibrant finishing touch.
How to Serve Spicy Caramelized Squash with Lemon and Hazelnuts Recipe

Garnishes
Fresh parsley isn’t just for color—it adds a delicate herbaceous note that enhances the dish’s overall brightness. For an extra burst of freshness, a few microgreens or a sprinkle of flaky sea salt can also elevate the final presentation.
Side Dishes
This Spicy Caramelized Squash with Lemon and Hazelnuts Recipe is a star on its own but also pairs beautifully with roasted chicken, grilled fish, or creamy grains like risotto or polenta. It brings a sweet-heat brightness that complements heartier mains perfectly.
Creative Ways to Present
Try serving the squash warm atop a bed of fresh arugula or mixed greens for a light salad twist. You can also incorporate it into grain bowls or even stuff it into warm pita bread with a dollop of tangy yogurt for a cozy, flavorful meal.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and store them in the refrigerator for up to 3 days. The flavors will deepen overnight, making for an even tastier second serving.
Freezing
If you want to keep this Spicy Caramelized Squash with Lemon and Hazelnuts Recipe on hand longer, it freezes well. Lay the roasted squash flat on a baking sheet to freeze individually before transferring to a freezer bag—this prevents clumping and makes portioning easy.
Reheating
To reheat, place the squash in a preheated oven at 350°F (175°C) for about 10 minutes, or until warmed through and crisp on the edges again. Avoid microwaving if possible, as this can make the squash soggy.
FAQs
Can I use a different type of squash?
Absolutely! While butternut squash is excellent for this recipe due to its sweetness and texture, you can also use delicata, kabocha, or acorn squash. Just adjust roasting times to ensure they become tender and caramelized.
How spicy is this recipe?
The cayenne pepper adds a gentle, warming heat that balances the sweetness. You can easily adjust the heat level by adding more or less cayenne depending on your preference or leaving it out for a milder dish.
Is this recipe vegan?
Yes, it’s fully vegan as long as you use maple syrup instead of honey. The ingredients are plant-based and rely on natural sweeteners and spices for their wonderful flavor.
Can I prepare this dish ahead of time?
You can roast the squash and toast the hazelnuts up to a day in advance and store them separately in the fridge. When ready to serve, combine, add lemon juice and zest, and reheat gently for the best taste.
What can I substitute for hazelnuts if I have allergies?
Walnuts, pecans, or toasted almonds are great alternatives. Each will add a unique nutty crunch that complements the caramelized squash beautifully.

Instructions
- Preheat Oven: Preheat your oven to 425°F (220°C) to prepare for roasting the squash, which will help develop a caramelized and tender texture.
